Samsung Electronics, which unveiled its very first Android-powered smartwatch around this time last year, said Thursday it plans to show off a standalone wrist-phone in Berlin next week that supports 3G wireless networks.

Unlike its previous models, this one will be able to make and receive calls without having to be tethered to a smartphone, as The Wall Street Journal first reported in May.

The new smartwatch will run on the company’s homegrown Tizen operating system. Samsung has recently run into a string of hiccups in getting the platform adopted in smartphones. In July, Samsung abruptly called off its plans to launch a Tizen-powered smartphone in Russia citing the need to further enhance the ecosystem.

The watch, to be called the “Gear S,” will come with basic health applications including a heart rate monitor and a pedometer. Samsung said it partnered with Nike to provide enhanced fitness software features. The Gear S has a 2-inch OLED, or organic light-emitting diode, screen and will be available in global markets from October.

The company didn’t disclose the price.

But Samsung won’t be alone in showcasing new wearable devices at the trade show next week. LG Electronics is planning to launch a new smartwatch model of its own. Both companies have launched multiple wrist-type electronic devices already this year, as they compete for a bigger slice in the fast-growing wearable devices market.

Many smartwatch models in the market today have rectangular screens including Samsung’s Gear series watches. One of the few exceptions so far had been Motorola’s Moto 360 smartwatch which features a round shaped display.

Other specifications for the G Watch R—microprocessor, memory and battery life—will be largely similar to what is available on LG’s G Watch.

LG is also taking aim at Samsung’s Galaxy Note smartphone/tablet hybrid during the trade show, planning to introduce a stylus pen that will go with its flagship G3 phone. The G3 phone has a 5.5-inch screen that nearly matches the screen size of the existing Galaxy Note phone.
